Harmonious is currently operated as a sole proprietorship. Sales are made by the individual operating the Harmonious trade name.

Accounts

A hosted instance requires a username and password. You are responsible for keeping your password private and for activity under your account. At account creation, save the recovery phrase shown once; it is the self-service way to reset a forgotten password. If you lose both your password and the recovery phrase, the operator may reset the account, but cannot recover the phrase. Do not impersonate another person, share an account, or use the service to record someone without their consent. The operator may suspend or remove accounts that abuse the service or put other users at risk. You can delete your account and its recordings from Settings; cancel any Paddle subscription first.

Subscription

Hosted access is a personal, non-transferable subscription for one person. Do not share an account. The service is provided as a hosted application; the source code is available under AGPL-3.0 for audit and review.

Payment

Hosted subscriptions are processed by Paddle, which acts as merchant of record and handles payment, applicable tax and invoices. Paddle receives your billing email and payment details under its own buyer terms and privacy policy; Harmonious does not receive or store card numbers. Plans renew automatically until cancelled. Cancel from Settings → Subscription → Manage billing; access continues until the end of the paid billing period unless applicable law requires otherwise.

Access

Hosted access is activated when Paddle confirms the subscription to this server, usually within seconds. If access does not appear, refresh Settings or contact support with the Paddle transaction number.

Refunds and cancellation

Hosted subscriptions can be cancelled any time; cancellation stops future renewals and access continues to the end of the paid period. Refunds are handled through Paddle. Nothing here limits mandatory statutory rights. See the refunds & cancellations policy.

No medical claims

Harmonious is a voice-training tool, not a medical device. It does not diagnose, treat or guarantee a voice outcome, a gender presentation, passing, or how any listener will perceive you. Stop exercises that cause pain, strain or hoarseness and seek qualified professional advice when needed.

Support, availability and changes

Support is provided on a reasonable-effort basis. The hosted service may be unavailable during maintenance, upgrades or outages. We may update the product and these terms; the version published with a release applies to that release. The operator is responsible for the server's availability, backups and data handling.

Privacy

See the privacy policy for data handling, account access, payment records and deletion, and the refunds & cancellations policy for hosted billing.
